3111mm son cums AND THE LIKE Application filed May 26,

To all whom it may concern:

Be it known that I, CHARLES'A. BRIGGS, a citizen ofthe United States, and a resident of Chino, in the county of San Bernardino and State of California, have invented a new and useful Improvement in a Binder for Cards and the like, of which the following is a specification.

The present invention relates generally to binders for cards, leaves and the like, and has specific reference to binders wherein the titles,'names or the like appearing in the marginal portions of the leaves or cards are visible as an index.

The general object of the invention is to provide for the detachable binding of one or more series of alphabetically arranged cards or leaves within a casing such as a book cover, file or the like, so that each series may be turned independently of the others as the leaf of a book and, additionally, to provide automatically for the prevention of a break or gap between any two adjacent leaves or cards of a series upon the removal of an intervening card, and furtherto permit the introduction of a new card. or leaf into any section of a series so as to occupy the same relative position as the other cards or leaves therein, and this without disturbing the relative positions of the other cards or leaves.

The above and other objects are accomplished by instrumentalities pointed out in the following specification.

The invention is clearly defined in the claims.

A satisfactory embodiment of the invention isfillustrated in the accompanying drawings forming part of the speclfication and in which Figure 1 is a plan view.

Figure 2 is a vertical cross-section on the line 11 of Figure 1.

Figure 3 is a view similar to Figure 1, showing the movable plate adjusted to a different position.

In the embodiment shown 5 is the base plate of metal or any other suitable material which, when the device is in use, will be permanently attached to a convenient part of a casing. If such casing be. a book, the base 5 will be permanently attached to the intervening section between the movable covers and will be similarly andconveniently attached to desirable portions of other forms of casings if these are used. 6 is a 1925. Serial No. 38,010.

' 8 of Which are herein shown as exten ing outwardly from the opposite end portions of base plate 5 and passing through similarly disposed angular shaped slots 9 in plate 7. As shown each side of each of the slots 9 extends outwardly from approximately the middle longitudinal line of plate 7 so that when said plate 7 is positioned as shown, the outer sides of the slots will function as cams and by reason of their angular contour plate 7 will move longitudinally and laterally outward for a distance and then longitudinally and laterally inward in the act of moving the plate for the length of either slot. The plate 6 carries a series of spaced semi-circular shaped prongs 10, the inner endsof which are suitably securedto the plate as by being riveted thereto. A series of mating or companion prongs 11 is carried by plate 7 and conform in contour to the prongs 10 and are secured to the plate 7 in a similar manner. noted, the prongs of each series are arranged in spaced relation and the spacing between any two adjacent prongs corresponds to the distance between the ends of slots 9. The

- prongs 10 and 11 are also constructed and arranged so that they will register and form continuations one of the other when the plate 7 is at either end of the movement afi'orded b r the pins 8, and it may be further state that the spacing between any two adjacentprongs in each series further corresponds to the width of the usual margin required for each leaf or card in the conventional types of indexed binders.

In operation the cards or leaves which, in width of course, are appreciably less than the length of either series of prongs, are arranged consecutively in alphabetical order. A series of such leaves or cards corresponding in length to the leaf of a book is had by As will be.

arranging the uppermost card so that the prongs.

card of the series extends to the opposite end of the casing. When the cards are so positioned the series may be moved as the leaf of a book by engaging the uppermost card from underneath and turning the same to the left and a similar result will be had in turning the series in the opposite direction by engaging the lower card or leaf. When it is desired to remove any particular card with the parts as shown by full lines in Figure 1, plate 7 is moved longitudinally until a gap or space is presented between the opposite series of prongs. In this position of the parts the prongs of one series will be offset with respect to the prongs of the other series and laterally spaced for a distance corresponding to the width of any of the slots. The lower card, for instance, may now be conveniently removed by turning the same to a vertical position and until it enters the space between the prongs after which it may be readily lifted, and the parts restored to their original positions by sliding plate 7. In the operation of removing one of the intermediate cards, the cards superimposed upon the one to be removed are turned over and upon the prongs 11, after which plate 7 is moved to provide for the space as previously described. The nearest wholly exposed card or the one to be removed is then turned and lifted through the space between the prongs. Now it will be obvious that if plate 7 were restored to its original position by a return movement and the cards held by the prongs thereof turned to their original positions, a gap or space would exist in the place left vacant by the removed card. \Vith the present invention, however, the presence of such gap or space will be prevented by causing a continuation of the longitudinal movement of plate 7 until the space between the prongs is closed at which time those of the prongs 10 then in registry with the prongs 11 will be those,

successively disposed to the prongs previously in registr so that when the several cards are returned from the prongs 11, their relative positions will be advanced toward one end of the series for a distance corresponding to the s acing between adjacent his will liave the effect of maintaining the several cards of the series in the same relative positions had before the removal of the aforesaid card.

Although Ihave shown and described one embodiment of my invention, it is to be understood that the same is susceptible of various changes; and I reserve the right to employ such as may come within the scope of the appended claims.

I claim:

1. In a temporary binder two plates arranged one a jacent to the other and each provided with a plurality of prongs, said prongs being arranged in adjacent spaced relation on said plates and normally registering, one of said plates being adapted to move longitudinally and laterally outward with respect to the other of said plates to provide a lateral separation of the prongs and then move longitudinally in the same direction and laterally inward to register the prongs thereof with successively disposed prongs on-the other plate, said plates being provided with means for guiding the movable plate in its movements.

2. In a temporary binder, a base plate, two plates arranged one adjacent to the other and superimposed on the base plate and each provided with a plurality of prongs arranged adjacent to one another and in spaced relation 'on said plates and normally registering, one of said superimposed plates being adapted to move longitudinally and laterally outward with respect to the other plate to provide a lateral separation of the prongs, and then longitudinally in the same direction and laterally inward to register the prongs thereof with successively disposed prongs on the other plate, said base and movable plates being provided with means for guiding the movable plate in its movements.

3. In a temporary binder, a base plate, two plates arranged one adjacent to the other and superimposed on the base plate and each provided with a plurality of prongs arranged adjacent to one another and in spaced relation onsaid lates and normally registering, one of sai superimposed lates being adapted to move longitudina y and laterally outward with respect to the other plate to provide a lateral separation of the pron s, and then longitudinally in the same irection and laterally inward to register the prongs thereof with successively disposed prongs .on the other plate, said base and movable plates being provided with pin and slot connections for guiding the movable plate in its movements.

CHARLES A. BRIGGS.
